Other Parts Discussed in Thread: AMC1100, AMC1200

How we should connect a D/A output,to the input of the aMC1100/1200?

In the d/s we saw solution only for res input.

    Hi Eli!

    What sort of application are you looking at here?  The AMC1100 and AMC1200 are intended to be used as current shunt monitors, which is why they are shown with the resistor in the data sheet.  The applied differential voltage swing is +/-250mV so that would limit what you can do from the input side of things.  Do you have a specific DAC in mind that you want to connect to the parts?

    Hi Tom,

     application: Using ispPAC-POWER1220AT8 to trim isolated DC/DC output voltage.

    1) The trim function output stage of pPAC-POWER1220AT8 is a DAC , so ,output voltage refer to input GND.

    2) The output voltage of the isolated  AMP is connected to the isolated DC/DC trim pin. So the output voltage of the isolated AMP is refer to the isolated DC/DC output voltage GND.

     

    I need isolated AMP with single P.S in each side .

     

    Please advise ASAP.
